Eikon Iron Ring of Aiming ★★★

Taken all the way down to base materials, one Eikon Iron Ring of Aiming is 3 crafting steps deep and needs 4 intermediates — Eikon Iron Ingot ×2, Grade 1 Dexterity Dissolvent ×1, Opal ×1 and 1 other — which resolve to 8 distinct raw materials totalling 29 units, plus 29 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,665 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 10 Wind Crystal, 9 Wind Cluster, 6 Fire Cluster and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 60 and Alchemist to Lv 53 — so no single class can finish it unaided.

6 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Smithsonite Ore (8:00, 20:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Eikon Iron Ingot has the widest use: 140 recipes call for it, spanning seven of the eight crafting classes.
